Please be advised that there is water flow through the Hays Lake Dam; the dam will remain open throughout the spring of 2025. This has resulted in higher-than-normal water flows along the Aguasabon River between the Hays Lake Dam and the Terrace Bay Marina at Lake Superior. The public is advised to exercise caution along this section of river.
Over the next few weeks there will be fluctuating water levels on Hays Lake. This is due to operating requirements and will result in unstable ice conditions. The public is advised to exercise extreme caution on and around the waterways of Hays Lake.
There was a flow completed planned at the Hays Lake Dam on Apr 17, 2025 to increase the flow to approximately 23 m3/s.
7 Day Ahead Water Level Forecast: 272.20m - 272.50m.
7 Day Ahead Flow Forecast Aguasabon GS: 5 - 30 m3/s.
